On my coach when new the video did not work right when I tried to feed it A/V Worked ok on RV but I could not get picture when I went the alternate, higher quality in theory route.
Finally I got a look at the backside of the big Toshiba TV The following chart represents the jacks... O= open X=Cable connectd
. . . out.. . .in 1. .in 2.
Video .X. . . . .O . . . O
Left . O . . . . X . . . O
Right .O . . . . X . . . O
Yup, they plugged the vide (Yellow)(lead into the OUT jack instead of the IN)
Same problem, Different pew.
